+## Non-interactive Prompt Mode
+
+You can run OpenCode in non-interactive mode by passing a prompt directly as a command-line argument. This is useful for scripting, automation, or when you want a quick answer without launching the full TUI.
+
+```bash
+# Run a single prompt and print the AI's response to the terminal
+opencode -p "Explain the use of context in Go"
+
+# Get response in JSON format
+opencode -p "Explain the use of context in Go" -f json
+
+# Run without showing the spinner (useful for scripts)
+opencode -p "Explain the use of context in Go" -q
+```
+
+In this mode, OpenCode will process your prompt, print the result to standard output, and then exit. All permissions are auto-approved for the session.
+
+By default, a spinner animation is displayed while the model is processing your query. You can disable this spinner with the `-q` or `--quiet` flag, which is particularly useful when running OpenCode from scripts or automated workflows.
+
+### Output Formats
+
+OpenCode supports the following output formats in non-interactive mode:
+
+| Format | Description                            |
+| ------ | -------------------------------------- |
+| `text` | Plain text output (default)            |
+| `json` | Output wrapped in a JSON object        |
+
+The output format is implemented as a strongly-typed `OutputFormat` in the codebase, ensuring type safety and validation when processing outputs.
+
 ## Command-line Flags

-| Flag      | Short | Description                   |
-| --------- | ----- | ----------------------------- |
-| `--help`  | `-h`  | Display help information      |
-| `--debug` | `-d`  | Enable debug mode             |
-| `--cwd`   | `-c`  | Set current working directory |

 - Clear identification of what each argument represents
 - Ability to use the same argument multiple times
